1610s, "skilled in a particular art or subject," formed in English from technic + -al (1), or in part from Greek tekhnikos "of art; systematic," in reference to persons "skillful, artistic," from tekhne "art, skill, craft" (see techno-).

Boxing technical knock-out (one in which the loser is not knocked out) is recorded from 1921; abbreviation TKO is from 1940s. Technical difficulty is from 1805.

1817, at first especially in criticism of art and music, from French technique "formal practical details in artistic expression" (18c.), noun use of technique (adj.) "of art, technical," from Greek tekhnikos "pertaining to art," from tekhne "art, skill, craft in work" (see techno-).

1919, coined by W.H. Smyth as a name for a new system of government by technical experts, from techno- + -cracy.

William Henry Smyth, a distinguished engineer of Berkeley, California, wrote at the close of the war a series of thoughtful papers for the New York magazine "Industrial Management", on the subject of "Technocracy". His thesis was the need of a Supreme National Council of Scientists to advise us how best to live, and how most efficiently to realize our individual aspirations and our national purpose. ["The Bookman," March 1922]

1610s, "a discourse or treatise on an art or the arts," from Greek tekhnologia "systematic treatment of an art, craft, or technique," originally referring to grammar, from tekhno- (see techno-) + -logy. The meaning "study of mechanical and industrial arts" (Century Dictionary, 1902, gives examples of "spinning, metal-working, or brewing") is first recorded 1859. High technology attested from 1964; short form high-tech is from 1972.

If the reader will consult such a book as Recent Economic Changes, by David A. Wells, published in 1889, he will find passages that, except for the dates and absolute amounts involved, might have been written by our technophobes (if I may coin a needed word) of today. [Henry Hazlitt, "Economics in One Lesson," 1952 edition]

1650s, "of or relating to building or construction," from Late Latin tectonicus, from Greek tektonikos "pertaining to building," from tekton (genitive tektonos) "builder, carpenter, woodworker; master in any art (sculpture, metal-work, writing)," from PIE root *teks- "to make" (see texture (n.)). The geological sense, "pertaining to the structure of the Earth's crust," is recorded from 1887.

"to spread" (new-mown grass for drying), c. 1300, from an unrecorded Old English *teddan or from a Scandinavian source akin to Old Norse teðja "to spread manure." Related to German verzetteln "to scatter, squander." Related: Tedding; tedder.

pet form of masc. proper names Edward, Edmund, and Theodore, with -y (3). Meaning "women's undergarment" (with lower-case t-) is recorded from 1924, of unknown origin, perhaps from some fancied resemblance to a teddy bear (q.v.), a theory that dates to 1929. In British slang phrase teddy boy (1954) it is short for Edward, from the preference of such youths for Edwardian styles (1901-10). Teddies (probably from Teddy Roosevelt) was one of the names given to U.S. troops in France in 1917.

1906, named for U.S. president Theodore "Teddy" Roosevelt (1858-1919), a noted big-game hunter, whose conservationist fervor inspired a comic illustrated poem in the "New York Times" of Jan. 7, 1906, about two bears named Teddy, whose names were transferred to two bears presented to the Bronx Zoo that year. The name was picked up by toy dealers in 1907 for a line of "Roosevelt bears" imported from Germany. Meaning "big, lovable person" first attested 1957, from the song popularized by Elvis Presley.

in golf, 1721, back-formation from teaz (1673), taken as a plural; a Scottish word of uncertain origin. The original form was a little heap of sand. The verb meaning "place a ball on a golf tee" is recorded from 1670s; figurative sense of "to make ready" (usually with up) is recorded from 1938. Teed off in the figurative sense of "angry, annoyed" is first recorded 1953, probably as a euphemism for p(iss)ed off.

"abound, swarm, be prolific," Old English teman (Mercian), tieman (West Saxon) "beget, give birth to, bring forth, produce, propagate," from Proto-Germanic *tau(h)mjan (denominative), from PIE *deuk- "to lead" (see duke (n.)). Related to team (n.) in its now-obsolete Old English sense of "family, brood of young animals." The meaning "abound, swarm" is first recorded 1590s, on the notion of "be full of as if ready to give birth." Related: Teemed; teeming.

also teen ager, teen-ager; 1922, derived noun from teenage (q.v.). The earlier word for this was teener, attested in American English from 1894, and teen had been used as a noun to mean "teen-aged person" in 1818, though this was not common before 20c.

1843, "to seesaw," alteration of Middle English titter "move unsteadily," probably from a Scandinavian source akin to Old Norse titra "to shake, shiver, totter, tremble," from Proto-Germanic *ti-tra- (cognates: German zittern "to tremble"). Meaning "move unsteadily, be on the edge of imbalance" is from 1844. Noun teeter-totter "see-saw" is attested from 1905 (earlier simply teeter, 1855, and titter-totter in same sense is from 1520s). Totter (n.) "board swing" is recorded from late 14c.; see totter (v.).

"pledged to total abstinence from intoxicating drink," 1834, possibly formed from total (adj.) with a reduplication of the initial T- for emphasis (T-totally "totally," though not in an abstinence sense, is recorded in Kentucky dialect from 1832 and is possibly older in Irish-English).

The use in temperance jargon was first noted September 1833 in a speech advocating total abstinence (from beer as well as wine and liquor) by Richard "Dicky" Turner, a working-man from Preston, England. Also said to have been introduced in 1827 in a New York temperance society which recorded a T after the signature of those who had pledged total abstinence, but contemporary evidence for this is wanting, and while Century Dictionary allows that "the word may have originated independently in the two countries," OED favors the British origin and ones that Webster (1847) calls teetotaler "a cant word formed in England."

commercially important synthetic polymer, 1945, proprietary name registered in U.S. by du Pont, from chemical name (poly)te(tra)fl(uoroethylene) + arbitrary ending -on; popularized as a coating of non-stick pans in 1960s; metaphoric extension, especially in reference to U.S. President Ronald Reagan, is attested from an Aug. 2, 1983, speech on the floor of Congress by Pat Schroeder.
